SLIDING GATE.

Specification of Letters Patent.

Patented Aug. 10, 1915.

Application filed March 8, 1915. Serial No. 12,779.

To all whom it may concern: I

Be it known that I, Encan G. HAKEMAN, a citizen of the United States, residing at Hartwick, in the county of Poweshiek and' State of Iowa, have invented new and useful Improvements in -Sliding Gates, of which the following is a specification.

My present invention pertains to gates of the sliding type; and it contemplates the provision in combination with a sliding gate, of simple, compact and durable means through the medium of which the gate may be expeditiously opened or closed by a person on horseback or in a vehicle, and this with the expenditure of but little efiort and in such manner that a dead-center is formed, calculated to prevent the endwise moi'ement of the gate by power opposed directly thereto.

The invention will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and forming part of this specification, in which:

Figure 1 is an elevation showing my novel gate as closed. Fig. 2 is ahorizontal section, partly broken away, of the same. Fig. 3 is a detail section illustrative of the means for throwing the gate-actuating lever and thereby facilitating the opening or closing of the gate.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The sliding gate 1 may be of any construction compatible with the purpose of my invention.

Fixed to and extending upwardly from the'cnd portions of the gate 1 are uprights 2 on the upper portions of which are circumferentiallygrooved wheels 3. These Wheels 3 are designed to travel on an overhead longitudinal rod 4; from which the gate is suspended. The said rod 4 is supported by posts 5, 6 and 7 fixed to and rising from the ground or any other suitable base, and by reference to Fig. 2 it will be seen that each of the posts 5 and 6 comprises spaced portions between which the gate 1 is movable.

8 is a fence or any other suitable bar which-extends to one side of the way controlled by the gate 1, as shown in Figs. 1

-and 2.

9, 9 are fixed posts arranged at opposite sides of the post 6 and at any suitable distance from the same. These posts have overhanging upper portions 10 in the outer portions of which a rock-shaft 11 is jour naled, this provision being made in order to permit of a vehicle being driven close to the posts 9 so that the occupant of the vehicl can conveniently grasp and manipulate one of the cranks 12 at the ends of the rock-shaft 11. The said rock-shaft 11 is also provided with a vertically-swinging bail-shaped crank 13, this crank 13 being disposed and movable between the spaced portions of the posts 6, as best/shown in Fig. 2. u

14 is a bail-shaped fixture on the upper edge of the gate 1 at an intermediate point in the length thereof.

15 is a fixed rod which extends across the and 16 is a lever constructed and arranged to swing "ertically in the plane of the gate 1, and to transmit motion from the crank 13 to the gate. The said lever 16 is pivoted at one end to the gate-fixture 14, is fulcrumcd at an intermediate point-in its length on the outer portion of the crank 13, and is provided at the opposite and free end with a bifurcated portion 17, designed and adapted to engage the fixed rod 15 after the manner shown in Fig. 3 incidental to the open-'- ing and closing movements of the gate.

Vhen the gate is closed as shown in Figs. 1 and 2, the axis of the shaft 11, the point of connection of the crank 13 to the lever 16, and the point of connection of said lever 16 to the fixture 14 are in a line-c. 8., in a dead center, and hence the gate cannot be movedendwise by power applied directly to the gate. This is also true when the gate is fully opened, the lever 16 atthat time extending toward the right from its point of connection to the fixture 14:. The same is materially advantageous because it effectually prevents casual opening of the gate or opening of the gate by live stock.

When a person in an approaching vehicle or on horseback desires to open the gate it is simply necessary for such person to grasp the adjacent crank 12 and rock the shaft 11 in the direction indicated by arrow in Fig.

1. When this is-done the crank 13 will raise the lever 16 and start the endwise movement of the gate 1 toward the left. When the bifurcated end 17 of the lever 16 engages the fixed rod 15, the free end of the lever will be thrown toward the right, whereupon com tinuedmovement of the rock-shaft 11 in the direction indicated, Will complete the opening of the gate and in so doing will move the lever 16 to a horizontal or approximately horizontal position above the gate, with its bifurcated end 17 at the right. After passing through the "gate-way, the occupant of the vehicle manipulates the other crank 12 and closes the gate by reversing the operation described.

'It will be noticed from the foregoing that the construction illustrated and described is simple, durable and reliable and is well adapted to Withstand exposure to the weather.

Having described my invention, what I claim and" desire to secure by Letters-Patout, is:

1. The combination of a sliding gate having a bail-shaped fixture on its upper edge at an intermediate point of its length, up rights fixed to and extending upwardly from the end portions of the gate and carry ing circumferentially-grooved wheels, an intermediate fixed post and outer fixed posts spaced from the intermediate post; the intermediate post and one outer post each having spaced portions, an overhead rod supported by said posts and supporting the said wheels, a fixed cross-rod extending between the portions of the intermediate post and arranged above the gate, fixed posts arra-ng at opposite sides of and spaced from the intermediate post and having upper overhanging portions, a vertically-swinging lever pivoted at one end to said fixture on the gate and having a bifurcated free end arranged to engage said fixed cross rod incidental to openingbr closing of the gate, and a rock-shaft disposed at right angles to the gate and journaled in the overhanging portions of the last-named post and in the spaced portions of the intermediate post and having a bail-shaped crank movable between said portions and connected to the lever and also having end cranks.

2. The combination of a sliding gate, means for supporting the same, a fixed crossrod supported in spaced relation to the gate,

' a suitably supported rock-shaft disposed at witnesses.
